- the registration array is now global instead of one by BTL.
- each framework have to declare the entries in the registration array reserved. Then
it have to define the internal way of sharing (or not) these entries between all
components. As an example, the PML will not share as there is only one active PML
at any moment, while the BTLs will have to. The tag is 8 bits long, the first 3
are reserved for the framework while the remaining 5 are use internally by each
framework.
- The registration function is optional. If a BTL do not provide such function,
nothing happens. However, in the case where such function is provided in the BTL
structure, it will be called by the BML, when a tag is registered.
Now, it's time for the second step... Converting OB1 from a switch based PML to an
active message one.

for dynamic selection of cpc methods based on what is available. It
also allows for inclusion/exclusions of methods. It even futher allows
for modifying the priorities of certain cpc methods to better determine
the optimal cpc method.
This patch also contains XRC compile time disablement (per Jeff's
patch).
At a high level, the cpc selections works by walking through each cpc
and allowing it to test to see if it is permissable to run on this
mpirun. It returns a priority if it is permissable or a -1 if not. All
of the cpc names and priorities are rolled into a string. This string
is then encapsulated in a message and passed around all the ompi
processes. Once received and unpacked, the list received is compared
to a local copy of the list. The connection method is chosen by
comparing the lists passed around to all nodes via modex with the list
generated locally. Any non-negative number is a potentially valid
connection method. The method below of determining the optimal
connection method is to take the cross-section of the two lists. The
highest single value (and the other side being non-negative) is selected
as the cpc method.

high prio QPs and low prio QPs) and because not all of them are polled each time
progrgess() is called (to save on latency) starvation is possible. The commit
fixes this. Now each channel is polled, but higher priority channels are polled
more often. Three new parameters are introduced that control polling ratios
between different channels.

This commit also cleans up the checkpoint and terminate case making it more
precise than before. Previously the application could make a small amount of
progress between checkpoint completion and application termination. Now the
application will make no progress at all in this time span.
Additional minor change:
- Start using OPAL_INT_TO_BOOL instead of if/else logic
